Diagnostic Menu
The “Diagnostic Menu” has several powerful functions that can help pinpoint a variety of
network problems. The Diagnostic menu can be used to determine connectivity to the network
as well as connectivity to the server or host computer.
RF Signal Strength
If the optional RF card is installed, the “RF Signal Strength” function allows the operator to
test the RF Link Status.
The “RF Quality” bar graph shows the RF signal strength of the closest Access Point. If this
bar graph is at 0% then there is no active Access Point in the area or your network settings are
wrong. Obviously the M7140 desktop terminal can not function without a good quality signal
from an Access Point.
The “Avg. Signal” bar graph indicates how much of the RF signal being received is usable. As
this percentage lowers, so will the TX Rate.
The “Avg. Noise” bar graph indicates how much of the RF signal is un-unusable. If the RF
signal is too low or the RF noise is too high, the M7140 desktop terminal will perform much
more slowly or not at all.
